Warriors' Gate

Warriors' Gate is the fifth serial of the 18th season of the British science fiction television series Doctor Who. It was written by Stephen Gallagher and was first broadcast in four weekly parts on BBC1 from 3 to 24 January 1981. The serial is set at an intersection between the universe of E-Space and the home universe of the alien time traveller the Fourth Doctor (Tom Baker). In the serial, the Doctor and his travelling companion Romana (Lalla Ward) seek to free the time-sensitive Tharils from a group of slavers led by Captain Rorvik (Clifford Rose). Warriors' Gate is the last of three loosely connected serials set in E-Space. It is the last serial to feature Ward as Romana and the last regular appearance of John Leeson as the voice of K9. Plot Inside the TARDIS, the Fourth Doctor, Romana, Adric, and K9, while travelling between E-Space and the normal universe (N-Space), become trapped in a white null space between the universes. Elsewhere in the void, a slave vessel, run by Captain Rorvik, has also become trapped. It uses members of the leonine Tharil race as their navigators. On becoming stuck, the current navigator, Biroc, escapes the ship and makes his way to the TARDIS on the winds of time. Biroc warns the TARDIS crew of Rorvik's treachery before disappearing. K9's memory wafers are shredded by the winds of time, leaving him functional but lacking long-term memories. The Doctor leaves on his own to explore the null space. He encounters some robots, called Gundans.
